Application filed August 20,1915. Serial No. 46,504.

To all whom it may concern:

Be it known that I, ROBERT A. DRAIs, a citizen of the United States, residing at Halleck, in the county of San Bernardino, State of California, have invented certain new and useful improvements in Devices for Cooling Engines; and l do declare the following to be a clear, `full, and exact def scription of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon,

" which form a part of this application.

This invention relatesto improvements in (a device for cooling,` engines and is more particularly adapted to be used in. connection with engines which are inclined to over-l heat and consequently necessitate a frequent filling of the radiator connected therewith. This device may be mounted in the position most accessibleto the driver of the vehicle and will receive the hot water from the radiator and inject a quantity of cold water in its place. lt is not necessary to use the device continuously, but only at such times as the engine becomes over-heated when the device may then be brought into action, and

due to the Afact that the hot water in the tank oit' the device has had a chance to be- 'come cooled, a quantity of cold water may then be quickly pumped into the hot radiafor rl`his improvement may be used in conn nection with the radiator without making any changes in any previous cooling system thatmay have been in use.

A further object or" die invention issto produce a simple and inexpensive `device tive for vthe purposes for which it is den signed. y

These objects, I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of the following;- specification and claims.

The ligure ofY the drawings' is a side ele 4 vation of an automobile showing the device as applied thereto.

Referring now more particularly to the characters of reference on the drawings, the numeral .l designates the 'footboard of the automobile upon which l have mounted a rectangular liquid containing receptacle 2 having a hand operated pump 3 of any ordinary construction placed thereon. Running from the pump 3, l `have provided a pipe 4.-

which leads downwardly toward the lower Instead of the overflow pipe commonly found, I have substituted in its place a pipe 7 leading downwardly and out of the back of the radiator tothe tank 2 into which it" empties, as at 8.

When it is desired to add cold water or a new supply of water to the radiator, the hand pump 3 will be Operated by the driver ofthe vehicle whereupon cold water will be pumped from the bottom of the tank i?. through the pipe 4 and into the radiator. As the natural action oli' cold water is to go always toward the bottom, a continuous operation of the pump 3 will force a new supply of cold water into the radiator and the over-supply of hot water will then be discharged through the overflow pipe 7 back into the top of the tank 2. l

By means of this construction, it is readily seen that a supply of cold water will be always ready for the radiator as well as any water that may be needed due to the loss caused by evaporation. The fact that the:

water will have a chance to stand in-the tank" a` device 'as substantially fulfils the objects yojf--theinvention asset forth herein.

A1""Vtlleile thisicspeciiication sets forth in deand yet one which will be exceedingly eeow tailthe present and preferred construction of thedevicestill in practice, such deviations from such detail may be resorted to as do not form `a departurelfrom the s irit of the invention as defined by -the"`appended claims.

Having thus described my invention, what l claim as new and luseful and desire to secure by Letters Patent' is:

l. The combination with a ymotor vehicle having a radiator, of an independent re ceptacle, aY pump operable to discharge from the bottom of saidreceptacle, a pipe connected with the pump and leading to and being' connected with the radiator, another pipe leading from the yradiator and dis from the receptacle may be pumpedfroin lll) .et or near the sent of the vehicle and arranged "to discharge material from *the bottom of the receptacle, e pipe .lending from' the pump end being' connected with Jthe .redia-tcignnd :i plpe leading from the radia- 'tor und discharging into the uppei` pn-rt of the receptacle, es described.

3. in combination With the circulation System for internal combustion engines, 1n

clnding a radiate?, of :in independent re ceptacle7 e pump7 operable. independently of the engine to discharge fromthe bottom 0l' ceptacle whereby water from the recept-nele may be pumped from the bottom thereof into the circulation system and flow from the top of the india-tor into the top of the receptacle.

ln testimony whereof I nifix my signature in presence of two Witnesses.
